Halbstufen-Reduktionspotentiale Bor-substituierter Benzolderivate / Half-Wave Reduction Potentials of Boron Substituted Benzene Derivatives

Abstract

The reversible one-electron insertion into mono- and 1,4-di-substituted benzene derivatives is favored by dialkoxyboron and especially by dialkylboron groups. The assumption that it should be the symmetric e2u benzene molecular orbital which is occupied in the resulting radical anions can be supported by comparison of ESR coupling constants.
